### Be someone TO COUNT ON in 2015

By any means of counting,
the number of incarcerated persons in the United States
is TOO LARGE

and the proportion of prisoners with BLACK SKIN
is TOO GREAT
and there is TOO MUCH VIOLENCE and DEATH in our prisons.

RESOLVE to stop the violence (RSVP)  in America's prisons!  Work for fair sentencing and Equal Justice!  Let your resolutions for the New Year 2015 be inspired by a poem;  the one below is from Poetry, 2009, found at poetryfoundation.org  -- and you may find more at Split This Rock.

To the voice of the retired warden of Huntsville Prison
(Texas death chamber)

Until wolf-light I will count my sheep,
One is perdu, two, qualm, three
Is sprawl, four, too late,

### A Fractal Poem

A fractal is an object that displays self-similarity -- roughly, this means that the parts have the same shape as the whole -- as in the following diagram which shows successive stages in the development of the "box fractal" (from Wolfram MathWorld).

Michigan poet Jack Ridl and I share an alma mater (Pennsylvania's Westminster College) and we recently connected when I found mathematical ideas in the poems in his collection Broken Symmetry  (Wayne State University Press, 2006); from that collection, here is "Fractals" -- offering us a poetic version of self-similar structure:

Fractals    by Jack Ridl

On this autumn afternoon, the light
falls across the last sentence in a letter,
just before the last movement of Brahms’
Fourth Symphony, a recording made more
than 20 years ago, the time when we were
looking for a house to rehabilitate, maybe

### A thousand Christmas trees

My email poem-a-day today from www.poets.org is "Christmas Trees" by Robert Frost (1874-1963); this 1916 poem includes some calculations and reflections based on the line:

“A thousand trees would come to thirty dollars.

Frost's poem has provoked me to thoughts of inflation and conservation; for the full poem, follow the link given with the title above.  And, if your time permits, go back to previous "Christmas" postings in this blog at these links:  23 December 201324 December 201221 December 201222 December 2011, and 2 September 2010.

### The gift of a poem

In this holiday season of giving, sometimes the gifts are poems -- and sometimes mathy poems.  A few days ago, "Zero" by Robert Creeley (1926-2005) arrived in an email from Francisco José Craveiro de Carvalho, a Portuguese mathematician who loves poetry and has translated many math-related poems into his native language -- a seeker and finder of such poems who shares them with me.  (See also 23 October 2010 and 17 September 2013.)  At this time of giving and receiving, enjoy playing with these thoughts of zero as nothing or something.

### The Girl Who Loved Triangles

I found this poem by Michigan poet Jackie Bartley when I was browsing old issues of albatross (edited by Richard Smyth) and she has give me permission to post it here.  Like Guillevic (see, for example, this earlier post), Bartley has found personalities in geometric figures.

To the Girl Who Loved Triangles     by Jackie Bartley

Triangulation:  Technique for establishing the distance between two points
using a triangle with at least one side of known length.

One girl in a friend's preschool class
loves the triangle.  Tanya's favorite shape,
the children call it.  Simple, three sided, at least

one slope inherent, slip-slide down

### Fractals -- poems and photos

Marc Frantz and Annalisa Crannell have written about mathematics and art (Viewpoints:  Mathematical Perspectives and Fractal Geometry in Art: Princeton University Press, 2011) and now Frantz (who is both a mathematician and an artist, a painter) has collaborated with a poet -- Robin Walthery Allen --  to develop a collection entitled Dance of Eye and Mind (not yet published).  I am honored to present a poem-photo pair from this exquisite collection.

What is in us that must reach the top,
that longs to look down upon the world as if a god?
Don’t we know that in this infinite space
the same rocks at the seashore know the secret of each peak?

### Our curve is a parabola

Found in the essay, "Intellect" (1841) --  these words by 19th century American philosopher and poet Ralph Waldo Emerson (1803-1882):

When we are young, we spend much time and pains
in filling our note-books with all definitions
of Religion, Love, Poetry, Politics, Art,
in the hope that, in the course of a few years,
we shall have condensed into our encyclopaedia
the net value of all the theories
at which the world has yet arrived.

But year after year our tables get no
completeness, and at last we discover
that our curve is a parabola,
whose arcs will never meet.

### A mathy Haiku

Found at the froth magazine website, this Haiku by Christopher Daniel Wallbank.

Mathematics

I, mathematics,
One plus root five over 2.
My soul is golden.

Note:  In mathematics, two quantities p and q (p>q) are in the golden ratio
if the ratio p/q is equal to the ratio (p+q)/q.  The value of the golden ratio --
often represented by the Greek letter phi (φ) -- is 1.618...  or (1+√5)/2.

Here is a link to another mathy froth poem, this one "Division" by Ryley-Sue.

### A scientist writes of scientists

Wilkes-Barre poet Richard Aston is many-faceted -- a teacher, an engineer, a textbook author, a technical writer.  And Aston writes of those whose passion he admires-- in his latest collection, Valley Voices (Foothills Publishing, 2012) we meet laborers, many of them miners from the Wyoming Valley where he makes his home.  Aston also writes of scientists and mathematicians -- and he has given permission for me to offer below his poems that feature Marie Curie, Isaac Newton, and Galileo Galilei.  With the mind of a scientist and the rhythms of poetry, Aston brings to us clear visions of these past lives.

Scientist     by Richard Aston

It took more than a figure, face, skin, and hair
for me to become Marie Curie,
wife of simple, smiling, selective, Pierre
who could recognize — because he was one — my genius.

### Poet as mathematician

Lillian Morrison (1917-2014) was a NYC poet and librarian whose work I first met in the poetry-with-math anthology, Against Infinity.  Here is one of her poems from that collection.

Poet as Mathematician    by Lillian Morrison

Having perceived the connexions, he seeks
the proof, the clean revelation in its

simplest form, never doubting that somewhere
waiting in the chaos, is the unique

elegance, the precise, airy structure,
defined, swift-lined, and indestructible.

Morrison's insightful poem disappoints me in one important way:  her mathematician-poet is "he."  Another Morrison poem, "The Locus of a Point," may be found in my posting for 15 September 2014.

### Geometry of Love

A couple of weeks ago my "Google Alert" linked me to a posting of a science poem concerning "the geometry of love."  The posting -- at The Finch and Pea -- is a poem that is both elegant and precise (and one that has been included in the anthology, Strange Attractors:  Poems of Love and Mathematics, that Sarah Glaz and I collected and edited several years ago).  Here it is:

The Definition of Love     by Andrew Marvell (England, 1621-1678)

My love is of a birth as rare
As ‘tis for object strange and high;
It was begotten by Despair
Upon Impossibility.

### Giving thanks for poems

As Thanksgiving approaches I am thankful not only for many blessings but also for the numbers I use to count them -- eight grandchildren, four children, two parents, one sister, one brother, an uncountable number of friends.  And I am thankful for poetry.  Here is one of my favorite math-related poems.

How to Find the Longest Distance Between Two Points

by James Kirkup (England, 1919 - 2009)

From eye to object no straight line is drawn,
Though love's quick pole directly kisses pole.
The luckless aeronaut feels earth and moon
Curve endlessly below, above the soul
His thought imagines, engineers in space.

## Friday, November 21, 2014

One of my daily emails results from a Google Alert -- which I have set up to let me know of new web-postings (or old information newly accessed) that contain the terms "mathematics" and "poetry." (Another online delight comes when I Google "mathematics poetry" (or "math poetry") and browse the images that occur at the top of the list that Google offers.  What fun!)
It is through a Google Alert notification that I learned of the poetry book It Ain't Over Till the Math Lady Sings by Michelle Whitehurst Goosby (Trafford, 2014).  This Math Lady was the subject of an article by Jennifer Calhoun in the Dotham Eagle (Dotham, AL)  -- and Calhoun put me in in touch with the poet who graciously offered permission for me to present one of her poems here.  Goosby is a teacher and the poem poses a number puzzle for readers to solve.

### In Praise of Fractals

Philosopher Emily Grosholz is also a poet -- a poet who often writes of mathematics. Tessellations Publishing has recently (2014) published her collection Proportions of the Heart:  Poems that Play with Mathematics (with illustrations by Robert Fathauer) and she has given me permission to present one of the fine poems from that collection.

### Imaginary Number

Last week (on November 6) I was invited to read some of my poems at the River Poets reading in Bloomsburg, PA (where I lived and taught for a bunch of years).  Among the friends that I had a chance to greet were Susan and Richard Brook -- and, from them, received this mathy poem by Pullitzer-Prize-winning-poet Vijay Seshadri.

The mountain that remains when the universe is destroyed
is not big and is not small.
Big and small are

comparative categories, and to what
could the mountain that remains when the universe is destroyed
be compared?

### In college she studied mathematics

In the third paragraph of the Wikipedia bio for Marguerite Duras (1914-1996), we read "At 17, Marguerite went to France, her parents' native country, where she began studying for a degree in mathematics."  I had the opportunity, several weeks ago at AFI Silver, to enjoy a screening of an exquisite restoration of "Hiroshima Mon Amour," a 1959 film for which Duras wrote the screenplay (nominated for an academy award).
At the website goodreads.com I found this mathy (and poetic) quote that I recognized as from the film:

### A big voice, Galway Kinnell (1927-2014)

Last week master poet Galway Kinnell died (NYTimes obituary).  One finds a detailed bio and a baker’s dozen of his best poems at the Poetry Foundation website -- do a search using the poet's name.  Many of Kinnell's poems are about nature -- somewhat in the way that mathematics may be about science  --  that is, he uses the images of nature to speak multiply of complex issues.  Here is a poem about identity that includes several math terms.

Along the one-dimensional straight line
there are points and segments
but no curves or squares.
In the flat plane of two dimensions
there are points and segments
and circles and squares.
In the vast space of three dimensions
there are points and segments
and squares and spheres.
In a space of four dimensions
there is more than

### Martin Gardner collected poems

Last week the Mathematical Association of America (MAA) had a special program honoring Martin Gardner (1914-2010); tomorrow (October 21) is the 100th anniversary of his birth.   The shelving in the MAA meeting room displayed copies of many of Gardner's approximately one hundred books.  However, none of the books displayed were books of poetry and, indeed, Gardner referred to himself as "an occasional versifier" but not a poet.  Nonetheless he helped to popularize OULIPO techniques in his monthly (1956-81) Scientific American column, "Mathematical Games," and he also was a collector and editor of anthologies, parodies, and annotated versions of familiar poetic works.  Here is a link to his Favorite Poetic Parodies.  And one may find Famous Poems from Bygone Days and The Annotated Casey at the Bat and half a dozen other titles by searching at amazon.com using "martin gardner poetry."

### Taken out of context . . .

Sometimes good lines fit so well into their poems that their individual merits go unrecognized.  And then, taken out of context, they can lead lives of their own.  Here is a start for a collection of such lines.

Mathematics: Everyone rolling dice and flinging Fibonacci, going to the opera, counting everything.

Fire: The number between four and five.

### Can poetry change the climate for frogs?

Poems affect our spirits as well as our minds. And Split This Rock is looking for poems that protest and witness, world-changing poems.  Go here for information about their Eighth Annual Poetry Contest (with submission deadline November 1, 2014).
Here in this blog, as I present connections between poetry and mathematics, I provide some poems of protest and advocacy.  I advocate attention to problems of climate change -- to keep our world habitable; I advocate full recognition of women in the sciences -- for a not dissimilar reason.  We must not waste our resources.

A special issue of the Journal of Mathematics and the Arts entitled "Poetry and Mathematics" is now available online at this link.  An introduction by guest editor Sarah Glaz is available (for free download) here.   In this opening piece, one of the items that Glaz includes is her own translation of a math-puzzle poem from Bhaskara's (1114-1185) Lilavati that is charming.  I offer it here:

Ten times the square root of a flock
of geese, seeing the clouds collect,
flew towards lake Manasa, one-eighth

But unconcerned, three couples frolicked
in the water amongst a multitude of
lotus flowers. Please tell, sweet girl,
how many geese were in the flock.

### Clearing the Air with a Poem

Every poem has a climate -- a collection of emotional tones that overlay and underlay its words. Today -- as the U.N. meets in NY to discuss the future climate of our planet -- I have been looking for mathy poems with a climate of advocacy, verses that let the world know that we must, soon and vigorously, take action to keep our earth habitable.
One of the things I found is a poem (involving a couple of numbers and mathy words) by Simon Armitage that is printed on material that cleanses the air around it by absorbing pollutants.  A small photo from the website of Sheffield University is shown below -- and I urge you to follow the Sheffield link for the story of the poem and this link to see the full poem more clearly and the story behind it.  Here is Armitage's opening stanza.

### Marching for Climate

Today I want to call attention to the growing global concern about climate change accentuated by the United Nations Climate Summit that opens September 23. Tomorrow (September 21) I will travel on a 6 AM bus  from Silver Spring to NYC to be part of the People's Climate March.  It is said that more than 500 buses of protesters are heading to New York. 29 marching bands will provide the soundtrack. 26 city blocks are being cordoned off for the march's line-up.   At the same time, more than 2,000 People's Climate events are taking place in over 160 countries around the world—from Hong Kong to Buenos Aires and from New York to San Francisco.

To have a small carbon footprint I will march tomorrow with only a small sign -- one that wears a 3x3-square reminder that dates back to a 1968 essay, "Tragedy of the Commons,"  by ecologist Garrett Hardin (1915-2003).

There  is  no
place to throw
that's  away.

WHY is it taking us so long to act to preserve a habitable planet?  Do we not care about the world we are leaving for our grandchildren?

### Remembering Lee Lorch

Lee Lorch was a mathematician known for his social activism on behalf of black Americans as well as for his mathematics. He died in February of this year in Toronto, at age 98.  A life-long communist and a life-long crusader.  Last Thursday I attended a memorial service  (organized by Joe Auslander, a poetry-lover who one day had introduced me to the work of Frank Dux) for Lorch -- sponsored by the Mathematical Association for America and held at the MAA Carriage House in Washington, DC.  Friends and colleagues of Lorch spoke of his positive energy and the ways that he had enriched the lives of students and colleagues, of friends and strangers.  One of the speakers, Linda Braddy, a staff member of the Mathematical Association of America (MAA), did not talk about Lorch but about strategies for opening mathematical doors (as he had done) to new students.

### Hailstone numbers shape a poem

One of my favorite mathy poets is Halifax mathematician Robert Dawson -- his work is complex and inventive, and fun to puzzle over.  Dawson's webpage at St Mary's University lists his mathematical activity; his poetry and fiction are available in several issues of the Journal of Humanistic Mathematics and in several postings for this blog (15 April 201230 November 2013, 2 March 2014) and in various other locations findable by Google.
Can a poem be written by following a formula?  Despite the tendency of most of us to say NO to this question we also may admit to the fact that a formula applied to words can lead to arrangements and thoughts not possible for us who write from our own learning and experiences.  How else to be REALLY NEW but to try a new method? Set a chimpanzee at a typewriter or apply a mathematical formula.
Below we offer Dawson's "Hailstone" and follow it with his explanation of how mathematics shaped the poem from its origin as a "found passage" from the beginning of Dickens' Great Expectations.

### Hypertext poetry

We computer-screen readers all know hypertext; when we read along in Wikipedia or some other online document and come across an underlined term whose font color is light blue -- at such a point we may decide to keep on reading as if we had not noticed the light blue "hyperlink," or we may locate our cursor on that text, click our mouse, and link to a new screen of visual information.
My first encounter with hypertext poetry was the work of Stephanie Strickland -- in her 1999 love poem, "The Ballad of Sand and Harry Soot," available at this link.  If you, however, are someone who is not yet comfortably familiar with hypertext poetry, I invite you to gain some experience with hyperlinked reading via a prose essay -- reading it first as a traditional essay and then exploring ways that hypertext can vary the experience of reading.

It was my good fortune last weekend to meet the sister-in-law of one of my neighbors, mathematician and Harvey Mudd professor, Rachel Levy.  Levy is also a blogger and her postings in Grandma Got STEM tell of achievements of women in science.
I have looked for a poem to pair with my mention here of  Grandma Got STEMAlthough the following poem by Tami Haaland (found at the Poetry Foundation website) is not mathematical, it nicely brings to life a relationship between a grandmother and granddaughter -- and we wish for both of them "places to explore beyond the frame."

### Poetry in Math Journals

The Mathematical Intelligencer (publisher of the poem by Gizem Karaali given below) and the Journal of Humanistic Mathematics (an online, open-access journal edited by Mark Huber and Gizem Karaali) are periodicals that include math-related poetry in each issue.  For example, in the most recent issue of JHM, we have these titles:

### My best dream is floating . . .

Today I want to urge you to visit several sites in addition to my blog.  For example, there is the recent announcement of 2014 Fields Medal (equivalent to a Nobel prize) winners -- the four winners include the first female mathematician (Maryam Mirzakhani) ever to be selected as a Fields Medalist (equivalent to a Nobel Prize) and a mathematician who loves poetry (Manjul Bhargava).
With the help of a "Google Alert" I found a YouTube video of Alexandria Marie reading "The Mathematics of Heartbreak" at a Dallas Poetry Slam.  A link in an email from Texas computer scientist,  Dylan Shell, alerted me to these mathematical lyrics (new words for old tunes) in a mathbabe posting by Cathy O'Neill.
As we have been floating from topic to topic, it may be apt to end with the final stanza of my relevantly titled poem:

### Narrated by a mathematician

Recently translated by Adam Morris, the novel With My Dog-Eyes (Melville House, 2014) by Brazilian writer Hilda Hilst (1930-2004) is narrated by a mathematician-poet. That fact of narration is what first drew me to the book. (See also this July 3 posting.)  And then there is (related in Morris's introduction to the translation) Hilst's sad life, perhaps mirrored in her characters.  These are the opening lines from the novel's narrator:

The cross on my brow
The facts of what I was
Of what I will be:
I was born a mathematician, a magician
I was born a poet.

### Squaring the Circle

Reminding us of the ancient unsolvable problem that so many attempted, the July/August 2014 issue of Poetry Magazine contains "Squaring the Circle," a poem by Philip Fried.  Here are the opening lines; please follow the Poetry Magazine link above to enjoy the full poem.

from  Squaring the Circle     by Philip Fried

It's a little-known fact that God's headgear --
A magician's collapsible silk top hat,
When viewed from Earth, from the bottom up

### Divided selves, some of them savvy

For social connections, it is desirable not to be pegged as a member of an outcast group.  And thus a mathematician is likely to have at least two selves -- one who lives in the world of mathematics and another separate social self that negotiates that rest-of-the-world where many fear and shun mathematics. I found a situation somewhat similar when I studied at Hunter College in Manhattan:  I needed a separate self who negotiated the city. The problem-solving farm girl who knew small towns well and big cities slightly seemed better equipped to adapt to city conversations than her fellow students could chat about anything west of the Hudson.  How many hundred miles must you drive to get to Pennsylvania? they wondered.  (The Delaware River boundary of PA is about 75 miles west of the George Washington Bridge.)
In this vein, I present a poem that focuses on the country vs city divide -- and it involves a square look and a number.

### A math prof's lament

The mathematical connection for this poem is the fact that it was inspired by regrets for a missed opportunity in a mathematics class -- an opportunity missed by me and thus by one of my students.  There are so many ways to be wrong!

Lament of a Professor
at the End of the Spring Semester     by JoAnne Growney

I took an extra step to bridge the gap
between us, blind to your matching backward step.
We've moved in tandem until I'm angry
at you, and at me — I thought you needed
would have changed the direction of our cadence
and given you a chance to lead the dance.

A poem about another of my students, "The Prince of Algebra" is available here.  And this link will take you to the poems in my collection, My Dance is Mathematics (Paper Kite Press, 2006).

### Fixing something wrong

If there's something
wrong with the third
act,   it's   really
in  the  first  act.

This quote from Billy Wilder, Austrian-born writer and film-director (1906-2002), reminds me of a similar observation I have made about my mathematical work -- when a reviewer notes a problem near the end, usually the fix is near the beginning.          And so it goes . . .

### Each equation is a playful catch . . .

A mathematician is probably too close to her subject matter to speak playfully about it -- and thus she, even more than others, appreciates a phrase like "each equation is a playful catch, like bees into a jar," offered by Lisa Rosenberg in the poem below.  In "Introduction to Methods of Mathematical Physics," Rosenberg uses a child's anxiety about insects as a way to describe fear of mathematics and offers a smidgen of respect for "those few" who are fearless.

Introduction to Methods of Mathematical Physics    by Lisa Rosenberg

You must develop a feeling for these symbols
that crawl across a page, for the text overrun

with scorpions.  Like those books about insects
you read as a child, scared to touch the magnified photos,

### Poems with "equation" in the title

One of the ways to explore this blog is to go to the right hand column and find the instruction, SEARCH.
A few moments ago I did this and entered the word "equation" and found a long list of links, many of the latter ones redundant since they are picking up archive listings of earlier postings.  But the early ones can be fun to explore.  Here are five of  the first six items that the SEARCH BOX produced.  And the first two of these links yield poems with "equation" in the title.  Enjoy!

### Mathematicians are not free to say . . .

The poetry of a mathematician is constrained by the definitions she knows from mathematics.  Even though all but one of the prime integers is odd, she cannot use the words "prime" and "odd" as if they are interchangeable.  She cannot use the words "rectangle" and "box" as synonyms.  But the ways that non-math poets dare to engage with math words can be delightful to mathematical ears and eyes.  For example:

### Palindromes

Palindromic numbers are not uncommon  -- recently (in the July 12 posting) power-of-eleven palindromes are mentioned.  Palindromic poems are more difficult to find but see, for example, the postings for October 6, 2010 and October 11, 2010.
At a  recent Kensington Row Bookshop poetry reading, Hailey Leithauser revealed that all but one of the poems in her recent collection Swoop (Graywolf Press, 2014) contain a palindrome.

And here are a couple of my favorite palindromic phrases:

(the impossible integer)
Never
odd or
even.

(the mathematician's answer when she is offered cake)
"I prefer pi."

### Prove It

After observing that

1  =  1
and         1 + 3  =  4
and         1 + 3 + 5  =  9
and         1 + 3 + 5 + 7  =  16
and         1 + 3 + 5 + 7 + 9  =  25

it seems easy to conclude that, for any positive integer n, the sum of the first n odd integers is n2.

### Looking back . . .

I have been visiting my hometown of Indiana, Pennsylvania and not finding time to complete a new post -- and so I have looked back.  On July 9, 2010 I offered a sonnet by Australian poet Jordie Albiston that begins with these lines:

math (after)

first you get the number-rush as anyone
might do      you watch your world turn to
nought      put your foot upon the path re
what cannot be said      I’ve heard before
. . .

I invite you to go to the original post and read the rest.

### Poetry as Pure Mathematics

A recent email from Portuguese mathematician-poet F J "Francisco" Craveiro de Carvalho brought a 40-year-old stanza to my attention. First published in the May, 1974 issue of POETRY Magazine, we have these enigmatic lines by William Virgil Davis.  Enjoy!

The Science of Numbers:  Or Poetry as Pure Mathematics

It is far better to subtract.  In poetry,
Division is the mistress we agree to sleep with.

### Mathematician and Poet

Should I do it?  Should I do a blog post on a novel by Brazilian poet Hilda Hilst (1930-2004) that I have begun to read but don't yet know how to understand?
Hilst's novel, With My Dog-Eyes, newly translated by Adam Morris (Melville House, 2014), attracted my attention because its narrator is a mathematician and a poet.  Here are the lines with which the novel begins:

from   With My Dog-Eyes     by Hilda Hilst

The cross on my brow
The facts of what I was
Of what I will be:
I was born a mathematician, a magician
I was born a poet.

### A recent butterfly effect

The term butterfly effect has entered everyday vocabulary from the mathematics of chaos theory and refers to the possibility of a major event (such as a tornado) starting from something so slight as the flutter of a butterfly wing. This sensitivity to small changes is a characteristic of chaotic systems.  Recent news in Science magazine (9 May 2014) has drawn my attention to sea butterflies -- and the effect that ocean acidification is having on the lives of these tiny, fragile creatures -- and the environmental warning that this portends.  From the details offered in Science, I have constructed this poem of 4x4 square-stanzas:

Warned by Sea Butterflies     by JoAnne Growney

Sea butterflies --
no larger than
a grain of sand,

### Of all geometries, feathery is best . . .

The title for this post comes from Twinzilla (The Word Works, 2014), by Charleston poet Barbara Hagerty.  The title character of this collection is one of several poetic personalities that inhabit Hagerty's verse, and she offers a playful view of life's dualities -- sometimes versed in mathematical terminology.  Here's a sample.

Twinzilla Cautions *     by Barbara G. S. Hagerty

Do not accept packages from unknown persons.
Beware non-native strangers who may be concealing
hazardous contraband "down there."
Question algebra.  Dismantle thoughts traveling
the brain's baggage carousel in parabolas.

### Is mathematics discovered or invented?

My neighbor, Glenn, is fond of asking math-folks that he meets the question "Is mathematics discovered or invented?" -- and when he asked the question of MAA lecturer William Dunham the response was one word, delivered with a smile, "Yes." The question of invention versus discovery -- which may apply to poetry or to mathematics  --  is thoughtfully considered in "Notes toward a Supreme Fiction" by Wallace Stevens (1879-1955); here are a few lines from that poem.

from It Must Give Pleasure,  VII     by Wallace Stevens

He imposes orders as he thinks of them,
As the fox and the snake do. It is a brave affair.
Next he builds capitols and in their corridors,

### Three thousand, and two

Here is a small poem richly vivid with the contrasts of opposites:

beside a stone three
thousand years old: two
red poppies of today

### Found: Elementary Calculus

Here is a poem by Saskatchewan poet Karen Solie.

Found     by Karen Solie

Elementary Calculus

From    Elementary Calculus  A. Keith and W. J. Donaldson.
Glasgow:  Gibson, 1960.

Speed (like distance)
is a magnitude and has no
direction; velocity (like displacement)

has magnitude and direction.

### Number theory is like poetry

Austrian-born Olga Taussky-Todd (1906-1995) was a noted and prolific mathematician who left her homeland for London in 1935 and moved on to California in 1945. Her best-known work was in the field of matrix theory (in England during World War II she started to use matrices to analyze vibrations of airplanes) and she also made important contributions to number theory. In the math-poetry anthology, Against Infinity, I found a poem by this outstanding mathematician.

### And Now I See . . .

One of the ways we overcome our nervous shyness about our disabilities is by talking about them, and writing about them.  And by encountering the poetry of Kathi Wolfe.  I enjoy her work out-loud -- she is a frequent performer of her poems at local DC-area venues  -- and on the page.
Kathi's "Blind Ambition" (in which she speaks of the monsters in arithmetic) is offered below; I first discovered this poem when it was posted by Split this Rock as poem of the week.

### Impossible Things Before Breakfast

Literary works by Charles Lutwidge Dodgson (1832-1898, aka Lewis Carroll) are crammed with mentions of mathematics.   One of my favorites (found here with numerous others, including "Ambition, Distraction, Uglification, Derision") is this exchange from Carroll's Alice in Wonderland.

"Alice laughed: "There's no use trying," she said; "one can't believe impossible things."
"I daresay you haven't had much practice," said the Queen.  "When I was younger, I always did it for half an hour a day.  Why, sometimes I've believed as many as six impossible things before breakfast."

### Behind the cards -- mathematics

A couple of weeks ago at an MAA math lecture by Alissa Crans on the Catalan numbers, I sat near card-trick mathematician Colm Mulcahy.  And I asked him if he knew any poems about card tricks and their mathematics.
Though he at first said "no," Mulcahy turned out to have a couple of connections up his sleeve.  From Matthew Wright he learned of "The Card Players" -- a colorful sonnet from Philip Larkin's 1974 collection High Windows and available here with selections of Adriaen Brouwer's art.
And Bruce Reznick reminded him of the lyrics for "The Gambler" by Kenny Rogers.  The complete lyrics may be found here; I include below a stanza that offers some instruction about counting.
